ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 764,551, dated July 12, 1904.

Application filed May 13, 1904. Serial N0. 207,727. (No model.)

To who"?! y GOP/087%: from the engine, as will presently more fully Be it known that LWILLIAM HERO Bo'r, J 17., appear. a citizen of the United States, residing at Rigid-1y secured to one face of the pedestal Ghent, in the county of Lyon and Stateof 4 is an annular thrust-block 13, the left-hand 5 Minnesota, have invented certain'new and useface of which extends obliquely to the axis of 5 5- fulImprovements in Rotary Engines; andl'do the shaft 6, so that the said wedge-block in hereby declare the following to be a full, clea1',. vertical cross-section is wedge shape. This and exact description of the invention, such as thrust'block is formed with an approximately 7 will enable others skilled in the art to which it endless hlade-channel 14-, the bottom of which 1 appertains to make and use the same.- extends in a plane at a right angle to the-axis 60 My invention relates to rotary engines, and of theshaft 6. The projecting portions of has for its object to simplify the construction" the prcmelling-blades 11 fitand work in this thereof and improve the operation thereof, as channel 14:. a In other words, the said chanhereinafter noted. nel has such form aswould be given to the The inventionconsists or toe/novel devices samewere it tobe cutout by rotation of the 5 and combinations of devices hereinafter dehead and blades 11. At one point-towit, scribed, and defined in the claims. as shown, the highestpoint-said channel 14 -The invention is illustrated inthe aceompanearly or entirely dis-appears, or, in other nying drawings, wherein like characters in'di- Words, is reduced to zero, while its maximum I cate like parts throughout the several views. depth is at itslowest point. 7

Figure 1 is avicw in vertical section, taken A rotary shaft-or member 15, which is set centrally and longitudinally through the enat an oblique angle to the axis of the shaft 6, gine. Fig. 2. is a detail in section on the line but which intersects the center of the spher- 00 00 of Fig. 1, some parts being brokenlaway. ic'al head 7 thereof, is pi'ovided with a project- 5 Fig. 3 is a face view of the conical head which ing bearing-cl'isk 16, which bears against the 75 carries a plurality of impelling-blades ,jFig. oblique face of the thrust-block 13 and roaisa face viewof a socalled oblique abut tates thereover with a tight joint. Tosup ment. Fig. 5 is a section on the linens m port this shaft 15 for rotary movement in the of Fig. i; and Fig.6 is a face-viewof aradiposition indicated. it is. as shown, provided 3 ally-slotted bearing-disk, parts thereof being with a countersunk bearing-box 17,- which rebroken away. ceives approximately one-half of the hearing-- The numerallindicatesa bed-plate having head 7. At its other end said shaft 15 is verticalbearing-pedestals 2, 3, 4., and 5. v shown as provided with a projecting spindle The numeral G-indicates a shaft, which is 18, which is seated in the bearingpedestal 5 journaled in the bearing-pedestals 2 and 3 and at its end is subject to athrust-screw 19, 5

and at its projecting rightdiand end,,as shown working through the head of said pedestal. inFig. 1, is provided with a spherical head or As shown, the bearing-box 17 is adapted to ball'7. At its other end said shaft is subject be adjusted by a nut'equippedwedge 20, seat to a thrust-screw 8, which. as shown,-works ed, in the shaft-15 and acting on a projecting 4 through the head of the pedestal Qand presses stem 21 of said hearing. The conical head 10 9 the loose washer 9 directly against the end of is provided-with fourimpelling-blades '11, set i said shaft. Between the head 7 and the p'edninety degrees apart. Hence at correspondestal 3 the shaft 6 is provided with a rigidlying points the 'bearing-disklti is formed with sccured jconical head 10, which is provided radial slots 22;: through which the impellingwitha pluralityiof propelling-blades 1l,which blades 13 work with close engagement. blades project laterally from the face of said 1 The steam or compressed air will be delivhead and lie in planesradiating from the axis ered to a small steam-chest 23 through a supthereof. Said shaft 6 is further shown as ply-pipe 24. Said S'GGfllTPCllGSlJ, as shown, is provided with a pulley 12, over which a belt applied to the pedestal' t and communicates "s (not shown) may be run to transmit motion with the extremity of the blade-cl'iannel 14 I through admission ports 25. A spring-v pressed distribution-valve 26 works within the steam-chest 23 and cooperates with the ports 25; the said valve being of such-length that when moved into intermediate position it will close bothof said ports. Said valve has a stem 27, which works outward through a stufiing-box on one end of the steam chest 23 and is attached to a rev'ersingdever 28, pivoted to the pedestal 4. At its lowered and deepest point the channel 1a is provided with an exhaust-port 29, whichv leads to'an exhaustpipe 30. I

As is evident, the rotation of one of the shafts 6 and 15 will 'causethe other to rotate,

since the impel ling-blades 11., working through exhaust-port, and at such point will be exhausted. The valve 26, being spring seated, will yield from its seat slightlyif at any time the steam or air should be compressed in advance of an in'pelling-blade.

As already stated, the engine describedis a reversible engine. If the engine were to be constructed to run in one direction only, the admission-port would be placed at one extremity of the channel 14 and the exhaustport would be placed at the other extremity thereof.

The engine described is extremely simple and cheap to build.

- cient for the purposes had in view;

It will of course be understood from What has already been-said that the engine is capable of modification within the scope of my invention'as herein set forth and claimed.

It will of course be understood that the engine, so called, when positively driven may presence of be used as a pump to force water or to compress air.

Nhat 1 claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In a rotary engine, the combination with It is thought to be eflia pair ofv rotary members having their axes at an angle to each other, one thereof having a radially-slotted bearing-disk, and the other having a head formed with impelling-blades working through the radial slots of said bearing-disk, a relatively fixed oblique abutment, with the face of which said bearing-disk engages, said abutment having a blade-channel,

the bottom of which lies in a plane intersecting the axis of said blade-equipped head at a right angle, thesaid. channel fitting said blades, and having a variable depth, substantially as described.

2. In a rotary engine, the combination with a pair of rotary members having their axes at an angle to each other, one thereof having'a radially-slotted bearing-disk, and the other having a head formed with impelling-blades working through the radial slots of said bear,- ing-disk, a fixed oblique abutment with'the face of which said bearing-disk engageasaid abutment having a blade-channel; the b0; am

,of which lies in a plane intersecting the axis of saidblade-equipped head at a r-ight'angle,-

said channel fitting said blades and having a variable depth, suitable admission and exhaust ports leading to and from said bladechannel, one admission-port opening into each extremity: thereof, and a valve cooperating with said admission-ports to open and close the same in reverse order,"whereby the en- 'gine may be-run in either direction, substantiallylas described.

3. in a rotary engine, the combination with the shaft 6, formed witha head 7, of a head 10 J secured to said shaft '6 andprovided with impelling-blades 11, the shaft 15 set at an angle to said shaft 6 and having a bearing engaging said shaft-head 7, said shaft 15 further having the bearing-disk 16, formed with radial slots 22through which the said blades 11 work,

the rigidly-supported abutment 13, with the' face of which said bearing-disk 16' engages, said abutment having the variable-depth bladechannel '14 fitting saidblades ll, andsuitable I admission and exhaust ports opening intoand from said channel 14;, substantially as described, v a

In testimony whereof-I afiix my signature in two witnesses. WILLIAM HERO BOT, JR.- Witne'sses':
